Underlined pin names and descriptions apply when the device is configured without a serial port interface, referred to as no SPI mode.
Pin function depends if the serial port is used to configure the AD9861 (called SPI mode) or if mode pins are used to configure the AD9861 (called No SPI mode). The
differences are indicated by the SPI and No SPI labels in the description column.
Some pin descriptions depend on the interface configuration, full-duplex (FD), half-duplex interleaved data (HD10), half-duplex parallel data (HD20), and a half-duplex
interface similar to the AD9860 and AD9862 data interface called clone mode (Clone). Clone mode requires a serial port interface.
